Starting at level 3, the armiger starts with a pool of armor token equal to his damage reduction roll in the beginning of combat. He gains 1 armor token for every 5 points of damage absorbed by his armor, 1 armor token for every attack that miss (ranged or melee), or 2 tokens for every round he takes no damage while threatened (this is in additional to all other armor token gathering methods). At level 7 to 14 the armiger gains 4 tokens for every round he takes zero damage while threatened and at level 15 and higher the armiger gains 6 tokens for every round he takes nil damage while threatened. You can’t simply ignore the armiger once he melees you (there are consequences).
I think the +1/no attacks hit needs to only count if they are threatened.
